Yes, also Fascism, and Communism. Capitalism unaffected.
Capitalism unaffected?

Taxes may be overspent and spent on wrong subjects, but people(myself included) never really want to pay for stuff that everybody (but not themselves specifically) benefits from and survives with. Capitalism has that stuff too. That's taxes for me.
No, it doesn't:
http://en.wikipedia.org/wiki/CapitalismCapitalism is an economic system based on the private ownership of capital goods and most natural resources, with the goal of making a profit. Elements central to capitalism include capital accumulation, competitive markets, and a price system.
Perhaps you're thinking of
State Capitalism.
its still not the same as blackboards, and having a whole bunch of very clever people around to ask.
This is true. But we also have discussion boards (for the clever people) and diagrams (which are probably better drawn than something whipped up in 5 minutes in front of the class).
do you know that some people, actually wants to pay taxes because they supports the system?
Wouldn't it be great to pick which programs you support, and not have to get the whole package, the welfare AND the bombs?
